NetherWorks, that's a great answer to ToolMaker! I second the "Freeing Memory of Unused textures". They should load only when they are needed. Yes OBJ files do have shortcomings. But, the fact that they are Text files allows for some interesting customizing. As far as "Reverse Normals" go. The info is there in OBJ. The problem usually comes when you export from a third app. So it's mainly dependant on the quality of the Export Plugin of the 3D modeler. For example, Harbware's OBJ plugs for Max are among the best out there. Scale, poly(Quads, Tris), Mats, groups, precision, rotation, face normals are all accounted for. 3ds I/O plugs are more stable & unified across the 3D Mods, probably cause it was been implemented earlier then OBJ. "- A clothing conforming program that can take a solid mesh and cut it into bodyparts to match a standard figure. Perhaps on the same vein as how The Tailor approximates morph vertices." Now that sounds very interesting! Marco
